Device for Connecting Battery Module Electrode Terminal and Terminal

Abstract

Provided is an apparatus for connecting between an electrode terminal of a battery module and a terminal capable of electrically connecting the electrode terminal and the terminal to each other by being press-fitted onto an outer side of the electrode terminal protruding outwardly of the battery module. The apparatus for connecting between an electrode terminal of a battery module and a terminal includes a socket terminal inserted and closely adhered onto the outer side of the electrode terminal and a socket coupled and closely adhered onto an outer side of the socket terminal and coupled to the terminal, such that the electrode terminal and the terminal are electrically connected to each other by the socket terminal and the socket.

Description

TECHNICAL FIELD[0001]The present invention relates to an apparatus for connecting between an electrode terminal of a battery module and a terminal capable of connecting the electrode terminal of the battery module and the terminal coupled to a power cable of an external device to each other.BACKGROUND ART[0002]Generally, since a secondary battery may be charged and discharged unlike a primary battery, the secondary battery has been applied to various fields such as a digital camera, a cellular phone, a laptop computer, and a hybrid vehicle and has been actively studied. An example of the secondary battery includes a nickel-cadmium battery, a nickel-metal hydride battery, a nickel-hydrogen battery, and a lithium secondary battery. In addition, among these secondary batteries, the lithium secondary battery having a high energy density and a discharging voltage has been mainly studied, and has been commercialized and widely used.[0003]Further, the secondary battery is configured in a f...

AI Technical Summary

Benefits of technology

[0020]In the apparatus for connecting between an electrode terminal of a battery module and a terminal, the electrode terminal of the battery module and the terminal coupled to the power cable may be connected to each other in the press-fitting scheme, such that a separate tool for electrically connecting the electrode terminal and the terminal to each other is not required, and connection is conveniently made.

[0021]In addition, the number of processes for connecting the electrode terminal and the terminal to each other and a time required for these processes may be decreased, and disassembling and assembling are simple, such that maintenance is easy.

[0022]In addition, quality problems such as a problem that a nut becomes loose, a contact defect, and the like, due to insufficiency of a fastening torque that may occur in a nut fastening scheme may be solved.

Problems solved by technology

In addition, a specific torque should be applied in order to tighten the nut, and disassembling and assembling are difficult at the time of performing a check due to occurrence of abnormality.
